# Purchasing and using the license

Defguard is available as an open-source solution with additional paid features. Some functionalities are available only with a valid license or are subject to usage limits, depending on the selected plan. Details about feature availability, limits, and pricing are provided on the [Pricing page](https://defguard.net/pricing/).

### Purchasing the license

If you would like to purchase a license, we offer two types of licenses:

1. **Subscription** that can be bought on <https://defguard.net/pricing/>
2. **Offline (which will not contact our license server) with a defined custom period** can be bought directly, please contact: sales @ defguard.net

#### Subscription

You can buy a monthly or yearly subscription on our website: <https://defguard.net/pricing/>.

After purchasing:

1. The license will be emailed to you on the email defined in the purchase form. Also there will be a second email with the invoice.
2. Each month (on the date the license expires) **Defguard core will contact our licensing server** and if the monthly payment was successful, our licensing server will **automatically issue a new license and the enterprise plan will be extended to new date.**

{% hint style="warning" %}
If your setup / firewall / network policy **doesn't allow that Defguard will contact our licensing server, please contact us for the** [**Offline license**](#offline-license)**.**
{% endhint %}

#### Offline license

Defguard is build with the highest security architecture in mind, thus there may be scenarios where you don't want any of the components to contact external services (eg. Defguard core will have no access to Internet).

Offline license can be also issued for any period of time, so another scenario is that you can buy the enterprise license for any duration you wish.

To obtain an offline Enterprise License please contact our sales at: **sales \[ a t ] defguard.net** and provide:

* the period for which you would like to obtain the license
* your company data and contact email address (for billing and license sharing)
* preferred payment method: bank wire transfer or card payment link

### Configuring Defguard with obtained license

To configure Defguard with the received license, please go to **Settings** -> License -> Enter license.
